Re: SAQ on Xmas Eve canceled.
- Hi All
See message from Grimeton.. http://www.alexander.n.se/
Transmission on Christmas Eve
We are sorry to announce that we have to cancel today's transmission. We did not get the speed control to work. We deeply regret this.
Anyway, we wish you all a Merry Christmas!
Ho Hum 80+ years you would be a bit shaky on your speed control I guess. Good luck Pete FMT.

This acts as a voltage limiter if connected across the the mic or line input used for the antenna on the sound card. High voltages can build on a wire antenna and can damage the SC front end. It is recommended. Good luck and 73 Pete FMT.
